Loss-correcting fault-tolerant quantum computing architecture for neutral atoms
A new arXiv preprint describes a fault-tolerant quantum computing architecture for neutral-atom arrays that treats qubit loss as a distinct error channel. The authors note that loss accumulates during operations and atom transport, and that standard error correction aimed at stochastic Pauli errors is not sufficient on this platform.

A loss-correcting architecture could be trialled on existing neutral-atom testbeds such as those from QuEra or Pasqal within two years by adding loss-aware decoding to their current rearrangement and mid-circuit measurement capabilities.
Loss accumulates during atom movement and gate operations, but neutral-atom platforms already perform atom rearrangement and measurement-based feedback. If the proposed correction overhead is moderate, adaptation is a control-stack and decoder change rather than new hardware.
